詳細

詳細

Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.
N-Acetyl-L-cysteine is an endogenous aminothiol which is a component of human plasma and urine. It finds use in clinical applications as a mucolytic agent typically administered by inhalation.

アプリケーション

N-Acetyl-L-cysteine may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations by liquid chromatography-mass spectrometry (LC-MS) and spectrophotometric techniques.

These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.
